-----------------------------------

             Summary: Add an option for uppercase/lowercase column name mapping between HCatalog
and RDBMS cloumn name list
                 Key: SQOOP-3029
                 URL: https://issues.apache.org/jira/browse/SQOOP-3029
             Project: Sqoop
          Issue Type: Improvement
            Reporter: Attila Szabo
             Fix For: 1.4.7


The current implementation of HCatalog related export works out of the box with RDBMS systems
(e.g. Oracle) if the column names match case sensitive, although in several cases the column
names are received as an UPPER_CASE list from the RDBMS, and thus the export fails, within
the ClassWriter.

Although the users have the possibility to define the name of the columns explicit with the
--columns option, in case of 100+ columns it's not practical.

It would be great to have an option which could do the matching in lower and UPPER case as
well. The start point for this implementation should start from SqoopHCatUtilities#configureHCat
method with respect to ensure HCatalog api is able to handle the different cased column names.
